Heart and blood vessel disease can lead to heart attacks and strokes. You can do a lot to prevent or slow down diabetes problems.

When diabetes affects the eye’s blood vessels it is called diabetic retinopathy. It is the sixth leading cause for blindess in India.

How can diabetes hurt my eyes?

High blood glucose and high blood pressure from diabetes can hurt four parts of your eye:

Retina: The retina is the lining at the back of the eye. The retina’s job is to sense light coming into the eye.

Vitreous: The vitreous is a jelly-like fluid that fills the back of the eye.

Lens:The lens is at the front of the eye. The lens focuses light on the retina.

Optic nerve:The optic nerve is the eye’s main nerve to the brain.

How can diabetes hurt the retinas of my eyes?

Retina damage happens slowly. Your retinas have tiny blood vessels that are easy to damage. Having high blood glucose and high blood pressure for a long time can damage these tiny blood vessels.

One of your eyes may be damaged more than the other. Or both eyes may have the same amount of damage.

What happens as diabetes retina problems get worse?

As diabetes retina problems get worse, new blood vessels grow. These new blood vessels are weak. They break easily and leak blood into the vitreous of your eye. The leaking blood keeps light from reaching the retina.
